摘要:

风速预测模型及其在风电场运行中的应用由于其作为清洁能源的优点而在文献中获得了显着的关注。在本文中,我们提出了时间序列机器学习方法称为随机森林回归预测风速变化。互信息和自相关的计算值表明,风速值依赖于过去的数据长达12小时。使用来自两周数据的集合训练随机森林模型,其中先前12小时值作为每个值的输入。计算出的均方根误差表明,用两周数据训练的模型可以用来对未来三年进行可靠的短期预测。

英文摘要:

Wind speed forecasting models and their application to wind farm operations are attaining remarkable attention in the literature because of its benefits as a clean energy source. In this paper, we suggested the time series machine learning approach called random forest regression for predicting wind speed variations. The computed values of mutual information and auto-correlation shows that wind speed values depend on the past data up to 12 hours. The random forest model was trained using ensemble from two weeks data with previous 12 hours values as input for every value. The computed root mean square error shows that model trained with two weeks data can be employed to make reliable short-term predictions up to three years ahead.
